INTRODUCTION
1 PRODUCT DESCRIPTION
DigiWolf is a paddle owmeter capable of measuring the rate of a uid in a hydraulic circuit, and it can display the results of these measurements.
The device can also be set to control the lling of a tank by stopping the introduction of liquid once the required quantity has been reached (this function
is possible only by connecting the owmeter to the Pump Stop Module or the relevant cable - Par. 2.4-2.5).
1.1 Intended use
This device is designed to work on agricultural machinery for crop spraying applications.
The machine is designed and built in compliance with EN ISO 14982 standard (Electromagnetic compatibility - Forestry and
farming machines), harmonized with 2004/108/EC Directive.
The owmeter must not be used to measure the passage of hydrocarbons, ammable, explosive or toxic liquids. The owmeter
is not suitable for contact with liquids for human consumption.
2 FLOWMETER ASSEMBLY
Install the owmeter at least 20 cm from the elements that could cause turbulence inside the tubes (valves, bends, constrictions, etc.).
The owmeter can be installed in a vertical or horizontal position.
CAUTION:
- Do not t the owmeter with the display facing down (Fig. 1).
- The system must have a ltering element with a lter of at least 50 mesh, together with a safety valve to limit use pressure at
the specied max. valve (Tab. 2 - Par. 2.3.1).
OK
Assemble the owmeter using the suitable mounting parts (Fig. 2): t the bolts (M8) in their seats, then make them slide to their stop position to prevent
them from coming out.
OK OK
NO!
Fig. 1
The owmeter body must be assembled with the arrow on the label facing the ow direction.

2.1 Monitor rotation
Fig. 3
INSTALLATION
In case of vertical assembly, to simplify the use of the DigiWolf it is possible to rotate the
monitor by 90° with respect to the body (Fig. 3).
1) Remove the fork from the monitor using a screwdriver.
2) Remove the monitor from the owmeter body.
Fig. 4
Fig. 5
Fig. 6
If the monitor is turned upside down, the letters A and B can be seen: these correspond to
the two possible monitor positions (parallel and perpendicular to the body).
DigiWolf is supplied with the sensor in position A (parallel to the body).
With the aid of a screwdriver, loosen the screw locking the sensor without removing it.
Rotate the sensor anti-clockwise until reaching B stop position.
Fig. 7
Tighten back the screw without forcing it. The monitor is ready to be tted in perpendicular position to the body.
Fit the monitor back on the owmeter body.

2.3.1 Hydraulic connection for brass/fork connections
Avoid bends and constrictions before connections and on tubes.
Use ARAG connections with their suitable OR with MALE CONNECTIONS [T connections - General Catalogue (Tab. 2)].
Do not use the owmeter at pressures greater than those listed in Table 2.
Regarding connections, use tubes and ttings properly sized for the operating pressure of the system.
CAUTION: For the implementation on already operating systems it is necessary to follow all safety rules described herein.
System assembly and start-up must be carried out by expert personnel according to the safety rules so as to ensure the same
safety level of the system the owmeter is going to be installed in.
After connection, check for the perfect sealing of the tubes and fork connections.

INSTALLATION
2.4 Electric connections
DigiWolf is designed to operate independently, but may be connected to ARAG devices (computers, monitors, displays) or equipment from
other manufacturers as long as they are set up for use with owmeters of this type.
DigiWolf can be powered by means of a generic power supply cable (cod. 4622BA50000.100 - not supplied), which does not allow the
operator to control lling functions directly from the device. Connections are listed in Table 3:
Cable colour Position Connection
Grey 1 GND
Brown 2 +12 VDC
Yellow/Green 3
Black 4 Pump control
For the use as lling owmeter, the DigiWolf must be connected to ARAG devices only.
IN CASE OF ELECTRIC ARC WELDING, MAKE SURE THAT THE POWER SUPPLY TO THE DEVICE IS DISCONNECTED; IF NECESSARY, DISCONNECT THE POWER SUPPLY CABLES.
ARAG is not liable for damages to the equipment, persons, animals or things caused by a wrong or unsuitable installation of the
owmeter. Failure to observe the above instructions automatically voids the warranty.
The DigiWolf connections on devices other than ARAG are indicated in Tab. 4.

To connect DigiWolf to Bravo 300/400 series computers and monitors use the "Pump Stop Kit" (code 4622BA50000.200) or the adapter
cable (code 4622BA50000.110 - ARAG Catalogue), which allows for connecting the DigiWolf 4-pole connector to the suitable Bravo
series computer 3-pole connector.
When connecting DigiWolf with external devices (Bravo 300/400, etc.), enter IN SUCH DEVICES the approximate constant according to the table below:

For any information about the connections with the Pump Stop Module (code 4622BA50000.200 - ARAG Catalogue), consult the rele-
vant use and maintenance manual (D20059), that can be downloaded at www.aragnet.com, in the Manuals section.
Fig. 11
In case the system features an ARAG 453 series 3-wire valve, we recommend to use an adapter cable (code 46220CBU01.100 - ARAG
Catalogue) which will replace the Pump Stop Module.
